I've been using Matt's service for a few weeks now and so far it works great. I'm using Residential Road Runner and I haven't needed to prioritize my traffic. However, if I'm downloading or uploading while on a call we start to breakup. Which is exactly what Matt had told me would happen.
Do you do any traffic shaping/rate limiting? I've found that somewhere between my modem and the head end there's a bunch of buffering that starts filling up when I push more bits upstream that the line can handle. (I've noticed this on a DSL/PPPoE box with SBC as well as a normal DSL bridged ethernet box that verizon gives out. I bet the PPPoE boxes
oceanic uses do this too). Its too bad they dont just drop the bits on the floor, because then tcp would react by limiting the amount of data it sent more quickly. Instead you get lot of latency on your uplink, which is sure to muck up your voice traffic. If I rate limit my uplink to just under the up limit my provider gives me, I hardly see any additional latency during a large xfer.
As for the phones, I've tried just about every linux based soft phone I can find and the only one I could get working reliably was the Debian unstable version of kphone. Its very simple to use and it just works. The only problem is that I haven't figured out how get an incoming call to ring on my speakers and not the USB headset.
I liked the iax phone for win32 a bit. Aren't their ports to other platforms like linux? Tim Newsham http://www.lava.net/~newsham/
